SPECIFICATION forming part of Letters. Patent No. 589,456, dated September 7, 1897. Applicati n filed February 8, 1897. Serial No. 622,500. (No model.)

To (tZZ whom/ it ntay concern:

Be it known that LFREDERICK V. Wrnrnns, a citizen of the United States of America, re-

siding in the city of New York, in the State of New York, have invented certain new and useful Improvements in Stand or Ran ge Boilcrs, of which the following is a specification.

My invention has relation to improvements in stand or range boilers; and the object is to is prevented from escaping, and this confined air becoming saturated with moisture eman ating from the heated water speedily rusts out the boiler-shell, greatly lessening the life of .the boiler and endangering its safety. My present invention is intended to obviate these results by withdrawing the moist air from the space above the water-line at the same time that the hot water is discharged through the hot-water-discharge pipe, and I accomplish this by the means illustrated in the accompanying drawings, wherein- Figure 1 is a central section of a portion of a horizontally-placed range-boiler and sectional View of the relief-pipe, the pipe-joint, and transversely arranged key fastening. Fig. 2 is a detail central section of the reliefpipe and pipe-joint connection held together by a circular washer and a key engaging in ways or seats in the flanges of the pipe-joint, the relief-pipe, and the washer. Fig. 3 is a modified construction showing the relief-pipe adapted to set about a warming-oven over the boiler.

Referring to the drawings, A designates a horizontally-laid range-boiler, which may be 4 5 of any approved construction, and, as shown in Fig. 3, is provided with the usual inlet-pipe 1 to admit cold water, a cold-water pipe 2, leading to a water-back, and a return hotwater pipe 3. In the head of the boileris a pipejoint opening 4i,wherein is secured a pipe-joint O designates the relief-pipe, consisting of a section of metal pipe formed, bent, or curved to reach from the inner end of the pipe-joint B to the upper surface of the boiler, as shown in Fig. 1 of the drawings. The upper end of this relief-pipe is formed with notches or scallops 9, through which the air finds entrance when the water is drawn off through the hotwater-discharge pipe. At a proper point in the upper portion of the relief-pipe are made ports 10, through which the water finds entrance into the hot-water pipe. The lower end of the relief-pipe 6 is formed with an annular flange 11, which tits in the bore of the pipe-joint B and sets against the annular end flange thereof, as shown, and to hold the reliefpipe securely in its proper fixed position in the pipe-joint and boiler a keyway 12 is formed through the pipe-joint B, in which a key 13 is fitted, which takes in a groove 14 in a keeper 15, the ends of which engage against the end of the relief-pipe, as indicated in Fig. 1 of the drawings. Other holding means may be used to secure the relief-pipe in position, such as is shown in Fig. 2 of the drawings, wherein a circular washer 16 is used to set against the end of the relief-pipe, and a key 17 is driven in-a slot or way 18 cut in the flanges of the united parts.

In Fig. 3 of the drawings I have illustrated the relief-pipe as formed to set in and about a warming-oven over the horizontally-disposed boiler. Referring to Fig. 3, it will be perceived that one end of the relief-pipe opens flush from the boiler, as at 19, and is then shaped to the contour of the warmingover and enters the boiler again adjacent to the end and extends into the boiler, stopping short of and adjacent to the inlet end of the hot-\vater-diseharge pipe, as shown at 20. It will be seen that when the current is established by opening a faucet at any point in the hot-waterdischarge pipe the suction created by the discharging water will also cre ate a current of air through the relief-pipe, and thus depleting the boiler of the saturated and moist air in the space between the boiler and the water-line.

To apply the invention in the iirst form, the relief-pipe is inserted loosely in the pipejoint section and the latter screwed up in place, and then the relief-pipe is turned up and the keeper inserted and keyed up to hold the pipe in fixed position. In the latter instance the relief-pipe is arranged in the threaded nuts, and after set in place the nuts are screwed up to seal the passages through the boiler.

lVhat I claim is- 1. In a horizontally-disposed range-boiler, an air-dischargin g relief-pipe having one end opening into the boiler above the water-line and the other end disposed below the waterline and arranged to direct the air into the hot-water-discharge pipe.

2. In a horizontally-arranged range-boiler, an air-discharging relief-pipe having one end leading into the hot-water-discharge pipe and the other end disposed above the waterdine and adapted to take the air from the boiler and discharge it through the hot-water-dis charge pipe.

3. In a horizontally-arranged range-boiler, a pipe-couplin g in the head of the boiler, and a detachable air-disehargin g relief-pipe in the boiler having one end opening into and secured to the pipe-coupling and its other end extending in the boiler and reaching above the water-line.

4. In a horizontally-arranged range-boiler, the combination of a pipejoint formed with exterior screw-threads and an intermediate annular collar, a bent relief-pipe having its lower end secured in the pipe-joint and its upper end arranged to reach above the waterline in the boiler.

5. The combination of a horizontally-arranged range-boiler, a hot-water-pipe joint detachably fixed in the head of the boiler, a relief-pipe to withdraw the air from the boiler, having one end in the said pipe-joint and the other end extended above the water-line in the boiler, and means to lock the relief-pipe to the pipe-join t.

In witness whereof I have hereto set my hand in the presence of two attesting wit- HGSSGS.
